Mesophilic Aeromonas strains express a polar flagellum in all culture conditions, and certain strains produce lateral flagella on semisolid media or on surfaces. Although Aeromonas lateral flagella have been described as a colonization factor, little is known about their organization and expression. Here we characterized the complete lateral flagellar gene cluster of Aeromonas hydrophila AH-3 c...
Aeromonas hydrophila, a zoonotic bacterium found in an expansive range of aquatic ecosystems, has been reported to cause severe diseases in fish, amphibians, reptiles, and mammals, including humans. Herein, we report the draft genome of the hypervirulent A. hydrophila strain HZAUAH isolated from a crucian in China.
Aeromonas hydrophila is an emerging pathogen of poikilothermic animals, from fish to mammals, including humans. Here, we report the whole-genome sequence of the A. hydrophila AH-3 strain, isolated from a fish farm goldfish septicemia outbreak in Spain, with a characterized polar and lateral flagellum glycosylation pattern.
Aeromonas hydrophila is the most common Aeromonas species causing infections in human and other animals such as amphibians, reptiles, fish and crustaceans. Pathogenesis of Aeromonas species have been reported to be associated with virulence factors such as lipopolysaccharides (LPS), bacterial toxins, bacterial secretion systems, flagella, and other surface molecules. Several mutant strains of A...
This study aimed to evaluate phagocytic and bactericidal activity of macrophages originated from murine J774 macrophage cell line against 26 strains of Aeromonas caviae, Aeromonas veronii biotype sobria and Aeromonas hydrophila isolated from human fecal specimens. The analysis of phagocytic index (PI) indicated these strains were phagocytosed in low numbers, below 1.1 x l0(-3) for 65% strains o...
The efficacy of eight routine enteric agars for supporting the growth of 32 strains of Aeromonas spp. (17 A. hydrophila strains, 8 A. sobria strains, and 7 A. caviae strains) was investigated. The plating efficiency of Aeromonas spp. on these media varied greatly (range, 0 to 100%), as did their colony size when compared with that on noninhibitory medium (5% sheep blood agar). Plating efficienc...
Aeromonas spp. are autochthonous in the aquatic ecosystem and some of them has been increasingly found, in patients with various diseases like enteritis, wound infection and even septicemia in amphibians, reptiles, frog, fish and in patients with impaired immunity. There are different virulence factors like aerolysin, hemolysins, cytotoxins, enterotoxins, proteolytic activity, lipolytic activit...
Aeromonas hydrophila pc104A is a moderately virulent strain isolated from the soil of a catfish pond in west Alabama in 2010. Its full genome is 5,023,829 bp. The availability of this genome will allow comparative genomics to identify the virulence genes that are important for pathogenesis or immunogens for the purpose of vaccine development.
A structural gene which codes for an extracellular protease in Aeromonas hydrophilia SO2/2 and D13 was cloned in Escherichia coli C600-1 by using pBR322 as a vector. The gene codes for a temperature-stable protease with a molecular mass of approximately 38,000 daltons. The protein was secreted to the periplasm of E. coli C600-1 and purified by osmotic shock. Cloned protease (P3) was identical i...
